Email Alert API Down
Receive an email notification when your API encounters problems.
APIs are the heart of modern applications. When an API goes down, multiple services are often impacted. A fast email alert lets you react before end users are affected.
MoniTao monitors your API endpoints and sends detailed alerts including error code, response time and response content if available.
Why Email Alerts for APIs
- Business impact: A payment API down means lost orders. An authentication API down blocks all users.
- Dependencies: Your APIs may be consumed by partners. A downtime affects the entire chain.
- Quick diagnosis: The email contains technical details to quickly identify the nature of the problem.
API Alert Content
- Affected endpoint: Exact URL of the failed API, with the HTTP method used.
- Error code: The HTTP code received (500, 502, 503, 504, timeout) with its message.
- Response excerpt: If the API returned a JSON error body, it's included in the alert.
Monitored Error Types
- Server errors (5xx): Server-side problems: crash, overload, application error.
- Timeouts: The API doesn't respond within the configured delay. Often a sign of saturation.
- Authentication errors: If configured, alerts on 401/403 indicating token or permission issues.
